ABSTRACT: Spectrum analyses are made on the morphology, wear and adjacent components aronnd diamond grits of iron-based diamond segment.Infuence of the key factors such as diamond grit distribution, grit size of iron powder

and strong carbonite elements upon the cutting performance are studied.The results show that, little proportion of

finer diamonds, finer iron grit and Ti contribute to improve the performance saw blade.

KEYWORDS: iron-base diamond circular saw key factor cutting performance
